What is the Army TST (Technical Selection Test)?
The Technical Selection Test (TST) is an examination used by the British Army to assess the mathematical and technical aptitude of candidates applying for technical roles. It is a crucial step for anyone hoping to enter trades within the Royal Engineers, Royal Electrical and Mechanical Engineers (REME), Royal Signals, and certain roles in the Royal Logistic Corps. The primary purpose of the TST is to ensure that candidates possess the foundational numerical skills required to succeed in demanding technical training. The question of whether you can use a calculator on the Army TST is therefore very important for preparation. Unlike general aptitude tests that measure cognitive potential, the TST specifically evaluates your existing knowledge of mathematics, similar to a GCSE-level exam.
Who Should Take the TST?
You will be required to take the TST if you list a technical trade as one of your job choices during the application process. This test is in addition to the Army Cognitive Test (ACT), which all applicants must take. Failing the TST does not disqualify you from joining the Army, but it will prevent you from pursuing a technical career path. Therefore, understanding the rules, such as whether you can use a calculator on the Army TST, is vital.
Common Misconceptions
A common misconception is that the TST is the same as the Army Cognitive Test (ACT) or the U.S. Army’s ASVAB. The TST is a separate, specialized test for British Army technical roles. Another point of confusion is about equipment. While some military tests strictly forbid calculators, the rules for the TST are specific. The frequent search query, “can you use a calculator on the Army TST,” highlights this uncertainty among candidates. The official answer is yes, a basic calculator is provided during the test.
Army TST Formula and Mathematical Explanation
The TST itself does not have a single “formula.” Instead, it is an assessment composed of multiple mathematical questions. The final score is simply the number of correct answers out of a total of 55 questions. The test must be completed in 45 minutes, meaning speed and accuracy are essential.
The calculation for your final score is:
TST Score = Number of Correct Answers
Understanding the structure is key, especially when considering the use of a calculator. Knowing you can use a calculator on the Army TST helps you focus on applying formulas rather than on manual arithmetic.
| Variable (Question Type) | Meaning | Number of Questions | Typical Range/Level |
|---|---|---|---|
| Arithmetic | Basic operations: addition, subtraction, multiplication, division with whole numbers, decimals, and fractions. | ~15-20 | GCSE Foundation/Intermediate |
| Percentages & Ratios | Calculating percentages, proportions, and scaling. | ~5-7 | GCSE Foundation/Intermediate |
| Algebra | Solving simultaneous equations, factorisation, and transposing formulae. | ~5-8 | GCSE Intermediate |
| Geometry & Measurement | Calculating area, volume, and angles. Metric unit conversions. | ~5-7 | GCSE Foundation/Intermediate |
| Data Interpretation | Reading and interpreting graphs and charts. | ~2-4 | GCSE Foundation/Intermediate |

Practical Examples (Real-World Use Cases)
Example 1: Calculating Minimum Score for a Vehicle Mechanic (REME)
A candidate wants to become a Vehicle Mechanic in the REME. They need to know the minimum TST score required. According to the official requirements, the minimum score is 16. The candidate takes a practice test and correctly answers 20 out of 55 questions. Since 20 is greater than 16, they are on track to qualify. The fact you can use a calculator on the Army TST makes tackling the decimal and fraction questions within the 45-minute time limit much more manageable.
Example 2: Preparing for an Avionics Technician Role (REME)
An applicant is aiming for the highly competitive role of Avionics Technician in the REME, which requires a minimum TST score of 29. This is a significant jump from the entry-level trades. The candidate knows they must excel in the algebra and simultaneous equations sections, which carry more weight. They practice these specific question types, using a calculator to speed up the process, ensuring they can solve complex problems quickly and accurately to meet the higher threshold.

Key Factors That Affect TST Results
Several factors can influence your performance on the TST. Understanding these can help you build a better preparation strategy.
- Mathematical Foundation: Your existing knowledge of GCSE-level math is the single most important factor. Rusty skills in fractions, algebra, or percentages will significantly impact your score.
- Time Management: With 55 questions in 45 minutes, you have less than a minute per question. Pacing is crucial. Knowing you can use a calculator on the Army TST helps, but you can’t rely on it for every step.
- Accuracy: The test is scored based on the number of correct answers. There is no penalty for wrong answers, so it is better to guess than to leave a question blank.
- Calculator Proficiency: While you can use a calculator on the Army TST, it’s a basic one. You need to be fast and efficient with it. Over-reliance can waste time.
- Stress Management: The test environment can be stressful. Practicing under timed conditions helps build confidence and reduces anxiety on the day.
- Trade Choice: The required score varies significantly by trade. A Fitter in the Royal Engineers may need a score of 21, while an Ammunition Technician in the RLC needs a 30. Your target score will dictate your preparation intensity.
Frequently Asked Questions (FAQ)
- 1. So, can you definitively use a calculator on the Army TST?
- Yes, for the British Army Technical Selection Test (TST), the use of a calculator is permitted, and one will be provided to you.
- 2. Is the TST the same as the ASVAB?
- No. The TST is a British Army test for technical roles. The ASVAB is the U.S. military’s vocational aptitude battery. Historically, calculators were not allowed on the ASVAB, though this policy has been under review.
- 3. What happens if I fail the TST?
- Failing the TST prevents you from entering a technical trade. You may be allowed one re-sit after a minimum period of 28 days.
- 4. How many questions are on the TST?
- The TST consists of 55 multiple-choice questions covering 28 different topic areas.
- 5. What is a passing score on the TST?
- There is no single “passing” score. The required score depends on the trade you are applying for, ranging from 16 to over 30.
- 6. Do I need to bring my own calculator?
- No, a basic calculator will be provided to you at the assessment center.
